Why Choose the EMAS SCM18NP1RC2 Capacitive Sensor?
The EMAS SCM18NP1RC2 is an industrial M18 capacitive proximity sensor designed for reliable non-contact detection of materials in automation, machinery and process-control applications. As part of the EMAS SCM series, it combines an adjustable 2–10 mm sensing distance with a PNP normally closed output and robust protection features for dependable operation.
Capacitive sensing technology allows the SCM18NP1RC2 to detect changes in capacitance caused by a target entering its sensing field. This makes capacitive sensors suitable for detecting many metallic and non-metallic materials, including applications involving plastics, glass, powders and liquids, subject to the target material and installation conditions.
The SCM18NP1RC2 operates from a 12–30 V DC supply and provides a PNP normally closed (PNP-NC) output with a maximum load current of 200 mA. Its non-flush M18 plastic cylindrical housing, 2 m cable and IP65 protection rating make it a practical choice for industrial sensing applications where compact, contactless detection is required.

Reliable Capacitive Detection for Industrial Automation
Capacitive proximity sensors detect objects by monitoring changes in an electrical field at the sensing face. Unlike inductive proximity sensors, which are primarily intended for metallic targets, capacitive sensing can be used with a broader range of materials, making it particularly useful for applications involving plastics, glass, powders, granules and liquids.
The EMAS SCM18NP1RC2 combines this versatile sensing principle with a 2–10 mm detection range, PNP-NC switching and a rugged non-flush M18 format. With no mechanical sensing contact required, the sensor avoids contact-related friction and wear while providing repeatable detection for automated production and process applications.
Typical Applications
- Industrial machinery and factory automation.
- Non-contact object presence detection.
- Plastic and non-metallic component detection.
- Level detection of compatible liquids and bulk materials.
- Packaging and production machinery.
- Conveyors and material handling equipment.
